Abstract:
A tunable delay line for radiofrequency or microwave frequency applications consists of at least one ridge waveguide in which the ridge is movable in the waveguide body so as to vary the width of an air gap defined between the longitudinal end surface of the ridge and a confronting member of the waveguide. The ridge is moved by an actuator external to the waveguide body.
